ProofOfExistence1

Proof of Existence

A proof of existence is evidence that proves that an object (a certificate, a CRL, signature value, hash value, etc.) existed at a specific time, which may be a time in the past. The presence of a given object at the current time is a proof of its existence at the current time. A suitable way of providing proof of existence of an object at a time in the past is to generate a time-stamp for that object.
ExpiredTimeStamp2

Expired time stamp

An expired time-stamp was used. Note that for expired time-stamps revocation information checks might not be possible.
